federal 10mm ammo yeah–having Hydra-Shok rounds in the best self-defense ammo isn’t a big surprise. The Hydra-Shok brand has always been a worthy contender when it comes to both effective penetration and efficient expansion.
This 180 grain Hydra-Shok round is relatively mild in terms of velocity. It moves at only roughly 1,000 FPS. This makes it about 100 FPS faster than a standard 40 S&W load with a 180-grain round.
However, it does penetrate 15.9 inches on average and expands to an impressive .61 inches. It’s a heavy little load that is controllable, especially from a full-sized gun. Penetration and expansion are the bullet’s job and your job is to ensure the round hits somewhere effective enough to ensure the penetration and expansion matters.
